1 Addiction (Substance Use Disorder) Provider in Ontario, CA

This directory includes 1 addiction (substance use disorder) provider in Ontario, CA from public NPPES records. Medicare activity is shown first because it can help identify providers with recent Medicare Part B billing volume, then the full directory keeps every published local provider available for lookup.

Medicare activity uses the most recently reported Medicare Part B service counts available in this dataset. It is a utilization signal, not a quality rating or recommendation. Providers without Medicare data still appear in the alphabetical directory.
